	Class Definition for Class 370 - MULTIPLEX COMMUNICATIONS
		The distinction between multiplexing and selective or telemetry is: in multiplexing, the information is unrestricted as to content, e.g., a teletype-writer which uses an alphabet to transmit unlimited information, whereas in selective or telemetry devices, the information is restricted as to content, e.g., a transducer measuring a single parameter.
		for multiplex in analog to or from digital conversion.
		Subject matter wherein the multiplex system has a primary and a backup line, and the backup is activated to routed information data when the primary channel is malfunctioning.
